cpupower suggests installation of non-existent linux-cloud-tools-generic package

[bugproxy]

Problem Description
===========================
cpupower suggests installation of non-existent linux-cloud-tools-generic package

Problem occurs on an IBM POWER 16.04 LTS system. Unknown whether it occurs on other architectures or later releases.

When run _without package "linux-tools-$(uname -r)" installed_, cpupower will issue a complaint, suggesting to install (among others), some linux-cloud-tools-*-generic packages:

$ cpupower
WARNING: cpupower not found for kernel 4.4.0-75

  You may need to install the following packages for this specific kernel:
    linux-tools-4.4.0-75-generic
    linux-cloud-tools-4.4.0-75-generic

  You may also want to install one of the following packages to keep up to date:
    linux-tools-generic
    linux-cloud-tools-generic

However, those linux-cloud-tools-*-generic package appear not to exist--at least not in the default repos.

Package linux-cloud-tools-common exists, but none of the *-generic packages are available:

$ apt-cache policy "linux-cloud-*"
$ cat xxx
linux-cloud-tools-common:
  Installed: (none)
  Candidate: 4.4.0-78.99
  Version table:
     4.4.0-78.99 500
        500 http://ports.ubuntu.com/ubuntu-ports xenial-proposed/main ppc64el Packages
     4.4.0-77.98 500
        500 http://us.ports.ubuntu.com/ubuntu-ports xenial-updates/main ppc64el Packages
     4.4.0-75.96 500
        500 http://us.ports.ubuntu.com/ubuntu-ports xenial-updates/main ppc64el Packages

[...]
     4.4.0-21.37 500
        500 http://us.ports.ubuntu.com/ubuntu-ports xenial/main ppc64el Packages

The cpupower command works (at least doesn't give this complaint) if the appropriate linux-tools-$(uname -r) (perhaps via linux-tools-generic) is installed, so the cloud package is maybe not needed (as least for some functionality).

I think the fix is to either:
a) supply the cloud packages for POWER, or
b) remove the non-existent packages from cpupower's complaint message.

---uname output---
Linux fs3 4.4.0-75-generic #96-Ubuntu SMP Thu Apr 20 09:55:30 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux

Machine Type = Firestone

---Steps to Reproduce---
 Install linux-tools-common but NOT linux-tools-*-generic on a POWER 16.04 LTS system, then run cpupower.

Userspace rpm: linux-tools-common

IBM, could you please validate this on 16.04.3 and report back here is this issue is fixed or still valid?

Problem still occurs on current 16.04, at least with the 4.4-series kernel: cpupower still suggests installation of "cloud" packages and they still don't exist (at least for for ppc64le):

$ dpkg -l | egrep 'linux-(tools|cloud-tools)'

My understanding is that "16.04.3" doesn't imply the 4.10 kernel.

Rather, both the 4.4 kernel series and the HWE kernel series (which would correspond to 4.10 in 16.04.3) are valid for 16.04.x.

Maybe this is fixed in the 4.10 HWE series (which I can't switch to at the moment) but not in the 4.4 "base" series?

i had the same problem with ubuntu 16.04.3, the packages suggested by cpupower wrapper are installing 4.4 tools (linux-tools-generic -> 4.4.0)
but the wrapper search for tools matching the kernel version

the cpupower wrapper make wrong suggestion, it should be :

  You may also want to install one of the following packages to keep up to date:
    linux-tools-generic-hwe-16.04
    linux-cloud-tools-generic-hwe-16.04

linux-tools-generic-hwe-16.04 is installing
linux-tools-4.10.0-35-generic and linux-hwe-tools-4.10.0-35
and i get the matching /usr/lib/linux-hwe-tools-4.10.0-35/cpupower for the /usr/bin/cpupower wrapper

Hi,
Is this issue fixed in the latest version ?

Thank you !
